The category must be added at the CreateOffer stage, prior to publishing the offer:

https://developer.ebay.com/api-docs/sell/inventory/resources/offer/methods/createOffer

While it is possible to create and save a partially completed offer as a draft, you must finish it before you move to publishing the offer. 

"This call creates an offer for a specific inventory item on a specific eBay marketplace. It is up to the sellers whether they want to create a complete offer (with all necessary details) right from the start, or sellers can provide only some information with the initial createOffer call, and then make one or more subsequent updateOffer calls to complete the offer and prepare to publish the offer. Upon first creating an offer, the following fields are required in the request payload: sku, marketplaceId, and (listing) format. "

createOffer and updateOffer are both deprecated as of 07/19/2024.

What replaces them?

Hi @river_house_books 

Inventory API calls like bulkCreateOffer, createOffer, getOffer, getOffers and updateOffer or Trading API calls like Add/Revise/Relist/Verify and GetItem family calls are not being deprecated. 

As mentioned in the API Deprecation Status page:

Only the economicOperator/EconomicOperator container in the Inventory API/ Trading API calls have been deprecated on 2024/07/19 and only the economicOperator/EconomicOperator container will be  decommissioned on January 30, 2025.
